hey i hear a ticking noise comming from the left side of the motor when im running between 1400-2000 rpm im thinking maybe an injector pump going south
the truck still has plenty of power though... it has also been running kind of rough almost like a pinging in the engine? i am running power service to keep the fuel from jelling the temp outside has been around 35 degrees all week. . the truck is a 98 12v any input would be great!
